I'm looking to purchase a cold air intake for my 02' f150, is the 77 series from K&N a good choice or are there other brands out there that do the same thing without the name? I'm looking to get more performance and a more ballsy sounding engine.

Also for anyone looking at this if you know where I could find a cheap replacement air compressor for a set of Hadley Air Horns that would be greatly appreciated.

Please and Thank You.
